Starting April 19th, 2016, our OneSimCard international SIM card comes with two phonenumbers: European (Estonia) and U.S. numbers. For Canada Customers it is European and Canadian numbers. For Australian customers it is European and Australia numbers and for UK customers it isEstonia and UK Mobile numbers.

The primary European numberis based in Estonia (country code +372). Estonia is a member of the European Union and one of the most high-tech and entrepreneurial societies in the world, especially when it comes to telecommunications. The world-famous program Skype was invented by Estonian developers.

The Free 30 days U.S., Canada, Australia and UK numbers are randomly assigned and you can choose to assign the number when you activate your SIM card or at a later date. Once your free PEN is assigned, it will be active for 30 days unless renewed monthly or yearly for a small cost. If instead you would like to choose your own U.S. or Canada, Australia or UK area code or a Toll Free number, you can order this separately.

You can order an unlimited number of Personal Extra Numbers (PEN) in many countries including:

* Indicates countries where local government regulations require proof of residency to purchase a PEN. PENs in these countries can be ordered for 6 and 12 month periods; PENs in all other countries are available for 1 month or longer.

Have phone numbers in as many as 61 different countries on one SIM card! You can also set your Caller ID to display a Personal Extra Number instead of your primary European number.

PLEASE NOTE: There is an additional charge of 20c/min to receive calls on your U.S. number or other PEN (except for a UK-Mobile PEN which only adds 25c per call). All SMS text messages must be sent to your primary European number, except for USA and Canada SMS Enabled PENs. Receiving SMS on USA or Canada SMS Enabled PENs costs $0.09 per SMS.

Free US and Canada PENs issued before December 8th 2014 will not accept text message. They could be used only for voice calls.

Starting June 3rd 2015, OneSimCard offers new USA and Canada PENs capable of receiving SMS. These PENs can be ordered separately and carry a charge of 9 cent per received SMS.

Starting January 1st 2018, OneSimCard offers special new USA - SMS for Bank verifications PENs. These USA and Canada PENs are capable of receiving SMS from most US and Canada financial institutions -most banks, Paypal, credit cards etc, as well as some apps like Uber ( but not from Whatsap). These numbersare also SIM VOIP capable and will work as a regular US PEN for incoming calls and SMS. These PENs are ordered separately.

Your OneSimCard international SIM card comes with both a European and U.S. number. To forward your regular U.S. numbers to the SIM, just set them to forward to the U.S. number that's included with your SIM card.

You can also order unlimited Personal Extra Numbers (PEN) - Local or Toll Free - in many different countries, including USA, Canada, UK, France, Italy and Spain. For example, if you work or live in the UK and want to keep receiving calls made to your regular UK numbers, just add a UK PEN to your SIM card and set up call forwarding to that new number.

Calls received through a PEN willbe charged an additional 20c/min to the incoming rate of the country you are in. The exception is calls received through a UK-Mobile PEN which is only charged an additional 25c per call.

Please Note: Your subscription to a Personal Extra Number starts the moment your order is shipped. If you do not need your PEN to be active right away, you can always wait and order a PEN later at any time by logging in to your account.

Different carriers use different ways of programming call forwarding. Below are instructions to setup call forwarding with various US wireless carriers. We urge you to test the call forwarding a few days prior to your trip, and to call your US wireless carrier for assistance if needed.

I have an unlocked iPhone 4, 5 or 6 and am receiving charges for SMS sent to a UK mobile number 447786205094. Why?

This is a known issue with Apple's Facetime and iMessage applications on iPhone 4, 5 and 6 phones. We recommend disabling Facetime and iMessage so it will not be able to automatically send SMS to this 447786205094 number. Any SMS sent to this number automatically by your phone can not be refunded by OneSimCard. Additional questions regarding iPhone 4 applications and how they communicate should be directed to Apple Support.

I have Range Roamer (Rangeroamer, Chit-Chat), I-Roam ( Iroam), Expo Mobile, Brighttel or iKappa SIM cards with numbers starting with +372. Can I switch to become OneSimCard customer?

If you currently have RangeRoamer (Range Roamer or Chit-Chat), I-Roam, Expo Mobile, Brighttel or iKappa SIM cards with the country code +372 ( Estonia) and can't get a service from the vendor you purchased the SIM card from and thus having problem, you can register the SIM with OneSimCard.com and keep the phonenumber of the SIM.

As a welcome bonus OneSimCard will post $10 free balance on your account. You will also get free 30 day US or Canada PEN.

Are there any international toll-free or local Common Access Numbers (CAN)?

OneSimCard international mobile service does not require dialing any access numbers when calling from international locations, you simply dial as you normally would when you're abroad. However, when somebody is calling to your OneSimCard phone there is an option for them to call you through a Toll Free or local number rather than dialing your European mobile number directly, which could be expensive for them. This call will instead be charged to your OneSimCard account at an additional 20c/min to the incoming rate in the country where you are receiving the call.

When someone calls you through a Common Access Number they receive a prompt where they then enter your primary European number starting with 372 to reach you. For a direct connection, we recommend adding a Personal Extra Number (PEN) instead.

At this time we have Toll Free and/or Local Common Access Numbers in the following countries:

Argentina

Australia

Austria

Argentina

Brazil

Canada

Cyprus

France

Germany

Greece

Hong Kong

Israel

Mexico

New Zealand

Russia

You can find these numbers in the User Guide or while logged in to your OneSimCard web account portal.

Yes. Your OneSimCard mobile number can be forwarded to almost any other number around the world! It's 100% free to forward your OneSimCard phonenumber to many countries, including to U.S. or Canadian numbers. Forwarding to some countries, as well as to satellite phones, will carry a forwarding charge as listed in the Rates & Coverage page on OneSimCard.com. There are a few exceptions where calls can not be forwarded to certain numbers.

To enable/disable call forwarding from your online account:

Log in at OneSimCard.com and go to the My SIM Cards menu. Select your SIM card number and enable/disable Call Forwarding on this screen.

What is the difference between OneSimCard Plus, OneSimCard Data & Roam and OneSimCard Europe & More SIM cards?

All 3 OneSimCard SIMs work in a very similar manner. They all use an Estonian Mobile Number as the primary number and offer a Free US or Canada PEN for 30 days. All OneSimCards also offer many additional features such as Global Concierge, 24/7 Live Technical Support, SIM VOIP and Apps for iPhone and Android.

The main difference between the 3 SIM cards is that OneSimCard Plus offers Voice and SMS Text Messaging in many more countries. The OneSimCard Data & Roam is recommended mostly for Internet Data on iPads, Smart Phones, Mi-FI devices and generally offers lower Internet Data Rates and Data Services in many more countries . For some countries like Canada, Cuba, Brazil and a few others, the OneSimCard Data & Roam offers lower calling rates.

The OneSimCard Europe & More was specially created for European travelers and offers our best calling rates to the US & Canada, from the 40 included countries, all with easy Direct Dialing, while OneSimCard Plus and OneSimCard Data & Roam utilize callback.

OneSimCard Plus, OneSimCard Data & Roam and OneSimCard Europe & More also operate on different networks in many countries.

The newly offered OneSimCard Europe & More does not use the callback to make an outgoing call.

With OneSimCard Plus or Data & Roam SIM:

Normally, when you make a call with OneSimCard the phonewill ring back within a few seconds after dialing and you will then get connected. You can eliminate this callback if you have a smarphone running Android (OS version 5 or below) by downloading and installing our OneSimCard Direct mobile app. Alternatively, you can purchase our Global Dual SIM Quad-Band GSM Unlocked International Cell Phone which has built-in software that automatically removes the callback.
